From 13.1 to 13.2

Now this is probably a shameful question,but…(Grateful if anybody can suggest a link faq/wiki page)

What can i do to upgrade (with zypper) to 13.2 ?
I have a lot of applications installed from unofficial repositories(really a lot of them)

Thanks

Only do the base repos first then once all the base stuff is done and updated re-enable the extra repos and only do zypper up otherwise you may pull in stuff that could break the system Don’t try to do it all in one step.

… and I suggest you back up your HD, first. Should always do backups first before any major work like that is done.
